Remove LVM metadata without killing the patient

[Brian McKee]

I have a working Hardy Heron box that *was* running LVM but when I
restored from backup I changed to regular partitions and UUID.
(Long story - I can relate why if you're really interested)

It seemed like I had it all working correctly, but a couple of days
later I noticed  an odd failed message on bootup.
After a bit of poking around I realized the LVM info still shows up if
you do a pvdisplay or vgdisplay etc.
even though the LVM partitions aren't actually there anymore.  I
surmise that LVM metadata must be tucked away somewhere on the disk
that it would survive formatting?

==> sudo vgscan
 Reading all physical volumes.  This may take a while...
 Found volume group "VOLUME-GROUP-1" using metadata type lvm2

lvscan and pvscan show the historical info too... but

==> sudo fdisk -l

Look Ma - no LVM!

How can I remove that LVM metadata without mucking up the regular,
working, in use, disk partitons ?

Comments appreciated,
